Men with higher intakes of dairy foods, especially milk, face a significantly higher risk of prostate cancer compared to men with lower intakes, according to a new study conducted by researchers at Loma Linda University Health. The study found no such associations between increased prostate cancer risk and intake of non-dairy calcium, suggesting substances other than calcium play a role in the risk dairy foods poses for prostate cancer.

“Our findings add important weight to other evidence associating dairy products, rather than non-dairy calcium, as a modifiable risk factor for prostate cancer,” said Gary Fraser, MBChB, PhD, the study’s principal investigator and professor at Loma Linda University School of Medicine and School of Public Health.
